I'd hate to see Cork tied to a single airline too, particularly one that doesn't provide interlining, but Malta would hardly be trampling on anyone's feet. It would be a surprising route choice though. I know Air Malta used to operate it a number of years ago, but the seats were pretty much sold to tour operators and it was only once weekly anyway. Also, as Malta isn't a Ryanair base, they'd have to cancel some more Dublin rotations to operate the route (or operate it as a W). At the moment I'm inclined to agree that it's likely to be a website glitch, especially as Athens is reported on that thread too and I can never imagine Ryanair operating into an airport with those charges!
